U.S. equity markets closed with gains on Wednesday, July 16th. Major technology stocks, including Amazon, Microsoft, Google, and Apple, performed strongly, contributing to the broader market's advance. This positive movement came as data showed U.S. producer prices unexpectedly fell in June, suggesting inflation may be cooling.

The Dow Jones Industrial Average rose by 150.37 points, or 0.29%, to close at 52,658.64. The Nasdaq Composite increased by 162.22 points, or 0.62%, finishing at 26,269.23. The S&P 500 index gained 28.81 points, or 0.38%, ending the session at 7,572.40.

Investors appeared to be reducing their exposure to key semiconductor stocks and rotating capital into some large-cap technology names. Notably, shares of Amazon, Microsoft, and Alphabet each rose by approximately 3%. Apple's stock also advanced by 4%.

Among chipmakers, Micron Technology shares fell 8%, while Lam Research declined by over 4%. Intel and Advanced Micro Devices dropped 4.4% and 3.5%, respectively. The VanEck Semiconductor ETF (SMH) closed 2% lower.

Market participants are assessing the inflation landscape. In a speech on Wednesday, New York Federal Reserve President John Williams stated there are "encouraging reasons to expect inflation has peaked and will gradually recede over the coming quarters."

Data released Wednesday showed the Producer Price Index for June unexpectedly declined by 0.3%, whereas economists had anticipated the monthly figure to remain unchanged. The report also indicated an annual inflation rate of 5.5%.

"I don't think this rules out a rate hike because if the goal is truly 2%, these numbers are still well above 2%," said Melissa Brown, Global Head of Investment Decision Research at SimCorp. "The market today may be overreacting to news on one side."

The PPI report followed Tuesday's Consumer Price Index data, which came in below expectations, bolstering hopes that the Federal Reserve may not need to be as aggressive with rate hikes this year. That report prompted traders to scale back expectations for imminent Fed policy tightening.

Although the perceived likelihood of a rate hike at the central bank's July meeting has decreased in recent days according to the CME FedWatch Tool, traders still anticipate a hike later this year. They see about a 60% probability of a quarter- or half-percentage point increase by the conclusion of the October meeting.

The market continues to monitor the latest developments in U.S.-Iran tensions. U.S. Central Command stated on platform X on Wednesday that the U.S. launched a second wave of strikes against Iran at 3 p.m. Eastern Time. Central Command said, "These strikes targeted Iran's military capabilities used to threaten the free passage of ships through the Strait of Hormuz, a critical international waterway for global trade."
